摘要 :
A paging system comprise paging buttons configured to transmit a first signal including a paging request; a server configured to: receive the first signal, identify which of the paging buttons transmit the first signal received by the server, and transmit to at least one portable device a second signal including information on an identifier corresponding to the identified paging button that transmits the first signal, and the paging request; and at least one portable device configured to: display the identifier corresponding to the identified paging button and/or the paging request based on the second signal, and transmit to the server a third signal in response to an acceptance input responded to the paging request. The server transmits to at least one portable device a fourth signal confirming that the portable device transmitting the third signal is matched to the identified paging button in response to the third signal.
